Abstract

Un procedimiento para la purificación de trihidrocarbilfosfina con al menos un grupo arilo y al menos un grupo alquilo o cicloalquilo en la molécula, a partir de una masa de reacción que comprende la trihidrocarbilfosfina, comprendiendo el procedimiento cristalizar la masa de reacción utilizando un disolvente constituido esencialmente por metanol. El procedimiento proporciona una producción inesperadamente eficaz de compuestos de trihidrocarbilfosfina con purezas de al menos el 97% en moles, y más preferiblemente de al menos aproximadamente el 99% en moles. Es otra realización de la invención una neomentildifenilfosfina con una pureza de al menos el 97% en moles producida mediante cristalización de neomentildifenilfosfina con una pureza inferior al 97% en moles, utilizando un disolvente constituido esencialmente por metanol.A process for the purification of trihydrocarbylphosphine with at least one aryl group and at least one alkyl or cycloalkyl group in the molecule, from a reaction mass comprising trihydrocarbylphosphine, the process comprising crystallizing the reaction mass using an essentially constituted solvent by methanol The process provides an unexpectedly effective production of trihydrocarbylphosphine compounds with purities of at least 97 mol%, and more preferably at least about 99 mol%. Another embodiment of the invention is a neomentyldiphenylphosphine with a purity of at least 97 mol% produced by crystallization of neomethyldiphenylphosphine with a purity of less than 97 mol%, using a solvent consisting essentially of methanol.
